Just a reminder at 2.30pm to 3.30pm Friday 03rd July 2009 (afternoon) is the repeated documentary "
We Are the Aliens" (2008). The programme talks of the ideas of
panspermia 
, and the theories by Fred Hoyle and Chandra Wickramasinghe during the 1960's. Good for a laugh and those who might like to find out where all the run-of-the-mill fringe scientists actually comes from! Bit of a giggle.
The BBC gives the description;
"In the 1960s, scientists Fred Hoyle and Chandra Wickramsinghe came up with the remarkable theory of panspermia: the belief that clouds of alien life forms sweeping through outer space could “infect” planets with life. At the time, they were ridiculed. But over the last decade, the field of panspermia has turned into a reputable science. In WE ARE THE ALIENS, groundbreaking research into panspermia is explored. NASA now has many departments investigating the possibility of life on other planets and how it could get to earth. Narrated by renowned actor Ian Holm, WE ARE THE ALIENS employs clever effects and graphics for an accessible "sci-fi" appeal complete with clips from classic science fiction films, but its core is true scientific research.
